Loudspeaker manufacturers, system installers & DIYers are increasingly developing custom FIR filters for DSP-driven loudspeakers due to the incredible flexibility FIR filtering provides in loudspeaker design & tuning, and the advantages that FIR offers for system integration.

Eclipse Audio’s FIR Designer software products can be used to create customized, powerful FIR and mixed FIR & IIR processing solutions that leverage both the efficiency of IIR filtering and the arbitrary response capabilities of FIR filtering. The products are ideal for creating loudspeaker tunings/presets with specific magnitude and phase characteristics, for matching different makes & models of loudspeakers in install systems & for performing system/room correction.

The latest addition to the Eclipse Audio product range – FIR Designer M – enables fast creation of complete loudspeaker presets for multi-way loudspeakers. It utilizes the same easy-to-follow workflow that made the original (single-channel) FIR Designer popular, but provides up to 6-way, simultaneous filter design. FIR filters & complete mixed FIR + IIR filter loudspeaker presets can be created for single & multi-way loudspeakers using multi-way loudspeaker driver measurements. The combined frequency response and time/frequency (wavelet) behavior can also be simulated.

FIR Designer M includes enhanced compatibility options for filter/preset export to Lake Processing, Powersoft & Linea Research, while still providing multiple export file format options for other FIR-capable processor & amplifier brands. Loudspeaker measurements in a wide variety of formats can be imported and automatically resampled to the filter design sample rate. A customizable measurement averaging function can optionally be used for spatial or level averaging to create more accurate, relevant measurements for the filter design workflow.

FIR Designer M is available for macOS & Windows, and free demo versions can be downloaded for experimentation. Compare the features of all Eclipse Audio products at eclipse.com/comparison-table.

I am looking to have 20 or so panelist mics setup. Typically I would run a gate on channels and or manually adjust volume on the current speaker. Is the automix feature what I need to look at to make my job easier? Obviously having 20 mics hot in a room is going to be […]

Hello Soundforums, I'm new to audio recording, need to do it for a project coming in 5 months and going to need to set up something that could capture sounds with as little noise as possible. My home is a pretty noisy place although it dies down at night and i could record if i […]

Hello, I will be honest this will be the only time I will use this forum but I need extreme help. I need everyone to gather their mental audio library and name this sound. This could help me IMMENSELY! You can also see all the current guesses here: Guess that Sound Guesses Wednesday, May 1: […]

A VIP speaker at international conferences has a quiet voice. His Schoeps CCM41 and Audix M1280B mics have LED reading lights on the booms and need to be away from his mouth. He can't wear a headmic or lav because of mobility concerns. I'm still looking for a mic that can pick up his voice […]

The latest iteration of my small PA system will require 4 crossover points. Funds are limited, but I have 2 x DBX Driverack PA units which will do the job, however auto EQ becomes messy. I note that the Behringer DCX2496LE crossover can be used as a mono 6-way, and has an AES input for […]
